Title: Zoltan Safar: Innovator in Data Transmission Technologies

Introduction

Zoltan Safar is a prominent inventor based in Atlanta, GA, known for his contributions to data transmission technologies. With a total of 2 patents, he has made significant advancements in the field, particularly in the areas of semi-single frequency networks and timing adjustment methods.

Latest Patents

One of his latest patents is focused on multipoint data transmission. This patent presents a semi-single frequency network (SFN) concept, where the same data signal is transmitted from multiple base stations to a mobile terminal simultaneously on the same frequency band. The transmitted signals are combined in the radio channel, allowing the mobile terminal to experience the signals as one cohesive signal propagated through a multipath channel. Each base station also transmits a specific pilot signal, enabling the mobile terminal to perform channel estimation and equalization of the received data signal.

Another notable patent by Zoltan Safar is related to transmitter timing adjustment. In this invention, a timing adjustment value is received, which is then divided into an integer portion and a fractional portion. The fractional portion is applied in the frequency domain by rotating a signal, while the integer portion is applied in the time domain by inserting or removing samples from the rotated signal. This innovative approach enhances the transmission process by ensuring precise timing adjustments.
